Abstract

Insulated-wire winding around a magnetic tape head core, constructed of stacked metallic laminae, is prevented from shorting to the core by folding oversize outer laminae over the sharp edges of the inner laminae.

Winding Short Prevention

Insulated-wire winding around a magnetic tape head core, constructed of stacked metallic laminae, is prevented from shorting to the core by folding oversize outer laminae over the sharp edges of the inner laminae.

A magnetic head core, carrying a winding, is constructed of a number of laminae. The two outer laminae are constructed to permit four folds to occur over the inner laminae. When the winding is placed over the lamination, the folded outer laminae protect the insulation from cutting by the lamination edges. The folded laminae also provide smooth uniform corners that facilitate the winding of the coil. A typical fold extends over 20% of the core width W.
